ASME SA213 T11 K11597 1.7335 Alloy Steel Seamless Tube For Heat Exchanger
T11 Tube Material is a low alloy ferritic stainless steel. There are carbon, silicon, manganese, nickel, phosphorus, chromium, sulfur and molybdenum in the content. The 0.5% carbon and 1% chromium bring the T11 Tube Material the good strength and corrosion resistance properties.
ASTM A213 T11 Tube is a boiler class stainless steel tube that is made from different material grades. The tubes are used in heat exchangers, super heaters and in boilers. The qualities of the pipes make them available for the high temperature services.
YUHONG Group is a manufacturer and supplier of these pipes in larger quantities. The ASME SA213 T11 Seamless Tube consists of carbon, manganese, phosphorous, sulfur, silicon, nickel, chromium and molybdenum. The composition provides the material with high tensile strength, high yield strength and high Brinell numbers.
A213: This indicates that the tube is manufactured according to ASTM A213 specifications, which cover seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
T11: This designates a specific alloy steel grade, which is part of the T series of alloys. T11 is a chromium-molybdenum alloy steel, known for its good weldability and high-temperature strength. The chemical composition typically includes approximately 1% chromium and 0.5% molybdenum, which helps improve its mechanical properties at elevated temperatures.
